Abstract: An apparatus for estimating bio-information may include: a bio-signal acquirer configured to acquire a bio-signal; and a processor configured to extract one or more first feature values from the bio-signal, determine a scale factor based on the first feature values, and to estimate bio-information based on the scale factor and the first feature values.

Abstract: A golf ball according to an embodiment of the present disclosure is covered with an injection-molded crosslinked polyurethane. The golf ball may have excellent scuff resistance and light resistance of a cover as well as excellent driving distance and spin by using a cover composition containing crosslinked polyurethane obtained by adding a crosslinking agent to thermoplastic polyurethane (TPU). A polyurethane cover composition according to an embodiment can make it possible to prepare a crosslinked polyurethane cover by injection molding without the burden of facility investment cost.

Abstract: A semiconductor package is disclosed. The semiconductor package includes a substrate with a first surface, a second surface and sidewalls. The package also includes backside metallization (BSM) over the second surface of the substrate. The semiconductor package is devoid of metal debris.

Abstract: A semiconductor package which is free of metal debris from backside metallization (BSM) is disclosed. The semiconductor package is singulated by performing a saw street open process from the frontside of the wafer and then includes a singulation process using a plasma etch from the backside of the wafer with BSM. The singulation process results in metal debris free packages.
